I have the Galaxy Tab 2 7.0, rooted with 4.0.4, and have not had any problems with it for the most part.
I recently downloaded Sketchbook Express to see how well the tablet could handle drawing. It handles it very well with one exception: the closer you get to drawing at a 45* angle, the more wavy the lines get. If I quickly swipe in that direction, it straightens out, but the slower I go, the more pronounced the waves or zig zags get. This happens using any of my fingers, the $20 Rocketfish stylus, and the $30 Wacom Bamboo stylus. All attempted on a freshly cleaned screen. I've also tried different apps with the same result. This guy had the same issue, as have others from what research I could pull up, but outside of unhelpful answers of "it's your stylus" (it's not), they all seem to have given up on getting help.
I've tried these apps on my friend's Evo 4G 3D, running Android 4.0.3, and had the same issue. I then tried on my rooted Xperia Play running Android 2.3.3 Gingerbread, and did not have this issue. I'm not entirely convinced it's an OS version that's making the difference, but I'm not able to find much information about the screens these devices use outside of "capacitive touch". I did learn that these screens use the corners to determine the location of input being received, so maybe moving directly in the direction of a corner is causing it to mess up?
Long story short, my questions are thus: is there any way to fix, calibrate, or compensate for this issue? Is it the screen, a hardware issue, or something else? Is there anything I can do?
Thanks for your time.

The problem is the digitizer. It's cheap. I think all of the g tabs have this issue. Mine is terrible drawing diagonal lines and even scrolling in landscape mode is choppy. Only way around it from what I can tell is to apply more finger surface area. That seems to fix it. But since you're using a stylus that's not possible. If you find a solution to calibrate the digitizer, please let me know!
I have the same exact problem and the same exact request. There must be some option to increase sensitivity to at least minimize this effect. It's the only flaw I can find on this otherwise wonderful device.
And honestly, for the prize it cost, I would expect this not to exist. But... I have it now and would like to be able to use it in it's full extent and power.
dammit
Nice to know I'm not the only one who notice that, but it's crazy how my finger seems preciser than my pen and even more, that in my Galaxy S the pen works perfectly. I was so happy to use some drawing apps on the tab but when I tried...
I tried in my Tab 7 2, then I'll try on my uncle's 10.1 just to check.
hello all,
just to report the same issue. i have same problem with my samsung galaxy tab 2 7" like you all here. i get this problem since the first time i bought it (about a month ago). drawing the lines and reading in landscape mode is choppy :crying: same as MrHyde03 said. i have been tested my cousin's tablet to draw diagonal line for comparison, he has galaxy tab p1000. and the line result i get, though his tab has wavy line too, but mine has more wavy line than his tablet. i didn't noticed his tablet has so wavy line, just a little. i did it with my finger.
i hope this issue can be fixed later.
could be a solution
I don't know if it's just for marketing or what, but maybe the original Samsung stylus is better for these screens.
I wish someone could certify this...
I bave The Same Problem... Vawy diagonal and arcs. The same pens and fingers works fine on my Asus TF 101...
I have the same problem

Hi guys, I have the same problem. Horrible response when i draw with a (cheap) stylus and perfect when i do it with my fingers. Has anyone tried adonit jot pro or Dagi ??? Maybe they increase the contact area and it solves the problem. If so, please tell us!!!
Thanks for reading and waiting for a solution.
I know this is an old post, but I can't just abandon my own thread! I've done quite a bit of research on this since making this post, and sadly, it's the way the screen is. Strange that my Xperia Play and Galaxy S3 phones can do this, but the Tab 2 was given such a cheap screen. I ended up selling it and putting the money towards a Note 10.1 with S-pen, which works as I would expect it to.
Hi Guys,
First post so go easy. Lurked the boards for a while now but only just registered. Hoping some one can help me out a little here, as I'm at my witts end now.
So I bought my xoom (MZ604..?) back in february second hand for £125 posted, it's a the 10.1" version and it's running android ICS. I bought it as i love my Samsung galaxy tab 7 but i think it lacks the screen size and the xoom seemed like a great price for a larger equivalent. I used it pretty much every day and it was awesome, never had any problems with it until...
My son decided to kick it off my lap onto the granite fireplace. The screen instantly went black and just didn't do anything. I could see a faint bbacklight on inside so I assumed it was the LCD panel that was broke, i could still here notifications and if i swiped in the right place i could also hear the tablet unlocking so the digitizer was ok too. I bought a water damaged xoom off ebay and harvested the screen to try and replace it and that wen ok, except i still had the same problem so I assumed that screen was broken too, oh well spares and repairs doesn't always work out lol...
So I bought a brand new LCD panel and fitted that yesterday, and it STILL won't work. However, the issue i now have is it won't turn on at all. I've taken it apart and put it back together multiple times to make sure it's all gone back in the right place etc. It's also charging ok, i put it on the dock and the light goes white, and then green after a while.
I'm at a loss here, as the new screen and xoom cost me nearly £100 so it's not really worth me paying any more as it's begining to seem like an endless pit of money.
TLDR:
Bought xoom
Son dropped xoom
Screen went black but tablet still worked
Bought 3nd hand xoom and swapped lcds
No joy with that
Bought brand new screen
charges but won't turn on now
Hoping someone on here can help me, i really don't want to throw it away as it's a fantastic device, but at the same time i can't keep plowing money into it if it won't work.
Thanks guys,
Uv.
Hope this is the right place for this conversation... sorry if its not
I have 3 tablets on the go here, my 6 year old had a RCA RCT6773W22 , he broke it, many times, i got into fixing the glass screens, lcd screens, battery swap out with a samsung phone battery b.c the battery was fried, and i was worried about the little soft battery blowing up as ive heard so much about it. BTW the samsung phone battery is awesome in there. lol
He killed the lcd on it again, wanted a tablet so bad he didnt want to wait a month for a new one from china, and we decided he could have an entire set of swap out items if he got another one. so he bought himself another one with his money, he broke that glass the same week. This time he got the RCA RCT6272W23 glass screen on these are weak. the old RCT6773w22 literally takes an beating and doesnt break easily.
So when he broke this new one, i took the mother board, and lcd out and put it into the old RCA because it still has a new glass/digitizer. Awesome it works great, and he has the old heavy duty screen that can take a beating
so heres my issue, i was given a proscan plt7044k - useless without the google store to my family
so i thought id be smart and put the mother board from the old old RCA into the proscan, because we had no digitizer or lcd for it. The parts all lined up hole for hole, screw for screw, i had nothing to lose, im learning. lol
I swapped in the RCA mother board thats it. the rest is Proscan. So i get it all wired up together, and fire it up. The screen resolution is to big for the tablet....i can only see roughly 1/3 of the full screen, and have to rotate it around to see certain areas....
Is there any way i can fix this, and get it to function right? or is this a case of a compatibility issue.... like maybe aspect ratio output vs screen capability?
not at dire straights here, just thought id get the second 'wow mom youre awesome' for fixing this tablet too...lol
thanks in advance for the input....

Hi and thank you for using XDA Assist
Sorry, but unfortunately this is not a right place to chat, i could only point you onto a right section of the forum, so i would suggest you to write it this again in the general forum:
Good luck!
Hey guys,
i'm posting this because I am going crazy about this and maybe you can help me figure it out (maybe it is something so dumb that I didn't think of it lol)
Well, here's the story:
Back in 2014, i used to have a Galaxy S (yeah, the first one of the S series, and yeah, it was already old when I had it in 2014). Pretty damn slow phone. Anyway, long story short, one day I went for a walk with it in my pocket, accidentally pulled my earphone's cord, the phone got out and went straight into the asphalt. This was the result:
https://imgur.com/90GNp2i (exhibit A)
Only the glass cracked, the LCD (is that an LCD screen? lol) wasn't affected. I always used a plastic screen cover that I believe helped keeping the glass around. Damage was pretty good but I didn't get too sad about it because a few weeks later I would be getting myself a Note 3. When that happened, the broken Galaxy S was laid to rest inside its box at the bottom of my wardrobe.
Fast forward to September 2017, when i sold the Note 3 to buy my current smartphone and had to use an old smartphone until the new one arrived. Grabbed the old Galaxy S and great!, working slow and heavy like a charm.
Kept using it for the next few days, until at some point whein messing around at the old phone's stored pictures I found exhibit A (that I had sent back in 2014 to my friends to show the damage) and I remembered what did the cracked screen look like. What the ****.
https://imgur.com/e7T0yMn (exhibit B)
Exhibit B is the picture I took with a friend's phone at the exact moment I realized that the screen was less broken (?) than before. Here are a few considerations about that:
1. The phone didn't leave its box, the box didn't leave the wardrobe. Nobody repaired the screen, and that can be told because of the two major crack points found in both pictures (first one in the bottom right corner of the phone, which may be a bit harder to see in the first picture, but it's there; and the one right above the center of the screen that can be better seen in exhibits C and D below)
2. The glass REALLY broke. It wasn't only the plastic screen protector, which btw I never replaced nor removed, it's still there holding the cracks (?) together.
3. There is no genius joke like "the second picture was taken before the first one and actually it was all a prank". No, the first pic is really from 2014 and the second is really from 2017. You can tell that by:
- looking at the Whatsapp design that really changed over the years; and
- well, believing me, because i really have no other pictures of it broken. hehe
These last two pictures I took tonight when I got crazy about that again (after the first euphoria about it last year, the phone went back into the wardrobe) and decided to post it here for you guys to tell me that the solution is really dumb and laugh at me.
https://imgur.com/vBH97Ar - exhibit C with white background
https://imgur.com/eWq7LXY - exhibit D with black background
So, XDA - wft has happened here? Is "screen semi-gluing itself back" an existing technology? Did the glass pieces only rearranged back to their normal place and the cracks are still there, but less visible? Did the plastic screen cover help? Should I look for more important things to worry about?
Thank you.
tl,dr - smartphone screen broke, found it less broken three years later.
Hello, I bought Samsung galaxy s7 in 2016 and its still working till now super fine. Today the screen just flickered some how and I think my phone is about to die.
I was thinking of buying a new phone.
I want it to be flat screen with aluminium frame in sides and back (glass in back is fine too) I rarely use camera too, I also want it to be super amoled. I want it to feel premium in the hand too.
Which phone you guys I should buy with these requirements?

Try clearing the system cache and a hard reset.
Is the battery still good? That may be the issue.
If exposed to water... that is the issue.
What price range? Any good phone generally comes with a good cam nowadays.
You can get a new Note 10+ N975U1 256gb, 12gb ram running on Q for $800. Picked one up last week, it's pristine.
I would stay away from anything running on 11 though.

I haven't cleared the system cache or did a hard reset in 2 years, so I am sure that would help!
The battery is still decent, I mean it's not as it used to be but it's doing fine.
What actually happens is that screen went crazy for like 10 sec (it flickered and shows lines and shaky pictures, then I pressed the power button and it won't back to normal) this is the first time this incident happens to me since I bought the phone. The phone is actually a beast, never lag, and feels premium, If there is still a fresh new one in the market I wouldn't hesitate to buy it again.
I am not sure about the price, to be honest, I think your suggestion is very good, I really lean to Samsung, But I don't like Note's :-(
I just want something like my current S7 (None edge) with let's say a bigger battery and a bigger screen.

If it's not repeatable it will be harder to troubleshoot. Try what I suggested. It's long overdue a system cache clearing. If it flickers again try plugging into the charger, if it stops it's likely the battery. Check for signs of battery swelling.
Try flexing the frame, gently, as well to check for a loose connection, display or mobo failure.
The 10+ is a beast and built solid. A case is mandatory for this corner hitting brick that also loves to face plant. It doesn't seem large to me at all anymore. It's very slim 7mm, so even with a good case it doesn't seem that large.
The spen is great as a remote shutter release and smart select is very handy which I use it for a lot now. The curve screen is the nesting place for One Handed Operation plus, no waste here.
The display is gorgeous (no rounded corners) and still one of the brightest with better color rendering than most newer phones. It's a flagship phone in every sense with snappy performance and about 10+ hours SOT. The Buds+ couple seamlessly with it. It still retains its on screen navigation buttons on Q. The Galaxy Store customization on the stock variants are the best on the planet.
Lol, I'm biased as it is my weapon of choice. I picked it over the N20 Ultra for a number of reasons a week ago.

Will try that! Thank you, Blackhawk!
I am checking the Samsung Galaxy S10+ it is really a big leap from S7, going to give that a thought, I really like the ceramic back, ceramic frame! also, the Dynamic Amoled seems fantastic! <3
And it still has the heart monitor!
You're welcome.
Water damage is insidious and pervasive. The faster you disconnect the battery and purge it, the better the outcome. It's possible there's some light corrosion on the ribbon cable contacts, reseating them may resolve it.
A very -little- WD-40 helps. Never get any solvents around LCD displays as it can poison them.
It is possible to salvage water soaked electronics with quick action. My Buds case went straight for a full hot cup of coffee, cream and sugar. Damn thing must have been Pav Tack guided, dead center of the cup. Straight to the bottom.
I couldn't disconnect the spot welded battery but I torn it apart, flushed with RO water, then with copious amounts of anhydrous isopropyl alcohol, dried. 2 years latter it remain functional.
I drank the coffee too
IMO when it comes to modding & rooting SAMSUNG phones aren't the best choice.
